Thanks fellas.
Here's a couple shots. Phil's rack sitting all the way back on Phil's rails (fantastic vendor). I have a shot of just the 2 stalks side-by-side, ast version vs bolas custom version, but they are on the iPhone and I don't feel like taking it off again.
Hindsight, I should have bought any similar backrest pad and made everything else myself. My stalk may not be perfect (took about 2 hours to make with grinder, hf 12 ton press, drill and appropriate tap), but I could have at least matched the build quality of the mount plate, if not exceeded it with the same tools I used for the stalk and saved myself $100. The mount plate is not symmetrical side-to-side and the overcuts in the corners from the handheld die grinder are clearly visible under the powder coat. Oh well.
Had to use an android to take and send pictures. I don't care for Apple products, for some reason my 2nd hand free old iphone isn't jiving with your site.
Don't have a real computer to fix the pix.
